Epson C82069* - Manual (Page 13)

Selecting PostScript
Because your printer is set to operate in one of the resident printer
modes, you need to change the mode setting through SelecType
before you can use the PostScript option.
If you are not familiar with SelecType, see your printer manual. You
may also find it helpful to refer to the Quick Reference card (located
at the back of the manual) whenever you use SelecType.
First, find the MODE or MODE ASSIGN menu in your SelecType
map. (The menu for changing the printer mode is not identical in all
printers.) You can change the printer mode to PS from these menus.
The following two sets of steps describe how to change the printer
mode for the EPL-4000/4100, ActionLaserII, and the EPL-7000/7100
printers. See your printer manual for more details.
